Filename Normalization for Oracle on Windows NT Platforms

In release 8.1.6 and higher, Oracle correctly normalizes filenames. However, you must use this procedure to normalize filenames in the control file and recovery catalog from earlier releases.

In releases prior to 8.1.6, a flawed filename normalization mechanism allowed two different filenames to refer to one physical file. DBMS_BACKUP_RESTORE corrects this so that Oracle accurately identifies all physical files referenced in the control file and the recovery catalog.
